TrinkCheck App: Trinkbedarf ermitteln und Wasser tracken inkl. Trink-Erinnerungen Die Gerolsteiner TrinkCheck App – dein ganz persönlicher Trink-Assistent! Mit der kostenlosen Trink-App von Gerolsteiner ganz einfach den Trinkbedarf bestimmen, Getränke tracken und ausreichend Wasser trinken. Außerdem bieten wir regelmäßig exklusive Gewinnspiele für unsere App-Nutzer:innen an!   Basierend auf deinen Körper- und Aktivitäts-Daten sowie dem Wetter bestimmt die TrinkCheck App durch wissenschaftliche Berechnungen der Sporthochschule Köln deinen täglichen, individuellen Flüssigkeitsbedarf. Steigt deine Aktivität oder die Tagestemperatur, steigt automatisch auch dein Bedarf an Flüssigkeit. Auch dank optionaler Trinkerinnerungen gehört vergessenes Trinken ab sofort der Vergangenheit an! Für eine optimale Nutzung kann die Trink-App mit Apple Health verbunden werden. Dadurch wird deine Aktivität direkt in die Trink-App übertragen, sodass du sie nicht täglich manuell eintragen musst. Zudem wird auch die Apple Watch unterstützt – so kannst du ganz bequem über die Watch deinen verbleibenden Trinkbedarf einsehen und Getränke hinzufügen. Das Hinzufügen von Getränken und Einsehen von Statistiken ist auch über den Startbildschirm, ohne Öffnen der App, per Widget möglich. Der Spaß-Faktor darf natürlich nicht fehlen: Mit unseren Challenges kannst du dich neuen Herausforderungen stellen und beispielsweise als „Zero Hero“ versuchen, eine Woche keine zuckerhaltigen Getränke zu trinken. Eine Challenge der besonderen Art: Im Wasser-Modus kannst du probieren, ausschließlich (Mineral-) Wasser zu trinken und deinem Körper damit etwas Gutes zu tun. Im normalen Modus sind natürlich alle Getränke erlaubt und du hast sogar die Möglichkeit, unter Angabe des Wassergehaltes eigene Getränke wie „alkoholfreies Bier“ oder „Strawberry Matcha“ hinzuzufügen. Unsere TrinkCheck App ist vollkommen kostenlos. Durch Registrierung in unserem Premium-Bereich kannst du deine Daten auf andere Geräte übertragen, deine vollständigen historischen Trinkstatistiken einsehen und an regelmäßigen, exklusiven Gewinnspielen teilnehmen. Funktionen der Gerolsteiner TrinkCheck App zusammengefasst: • Blitzschnelles Getränke-Tracking durch einfaches Hinzufügen der Getränke, sowie Anzeige der häufig getrunkenen Getränke. • Manuell einstellbare Getränkemengen – so kannst du die App perfekt auf dich und deine Trink-Gewohnheiten abstimmen. • Auswahl aus 12 Getränkekategorien wie Mineralwasser, Kaffee, Limonade oder Milch. Zusätzlich Erstellen eigener Getränke unter Angabe des Wasser-Gehaltes. • Trinkerinnerung: Lass dich benachrichtigen, wenn es Zeit ist, etwas zu trinken. • Fortschritts-Anzeige der getrunkenen Menge im Verhältnis zum individuellen Tagesbedarf. • Trink-Statistiken für Woche und Monat inkl. der Möglichkeit, nachträglich Getränke hinzuzufügen. • Extra-Motivation durch Challenges, die du individuell nach Level und Herausforderung starten kannst – z. B. wenn du auf Koffein verzichten möchtest. • Viele hilfreiche Beiträge rund um die Themen Ernährung und Fitness – optimal für Sportler:innen und alle, denen ausreichendes Trinken und ein gesunder Lebensstil wichtig sind.
